In July 1943, Mussolini was deposed by a revolt within his own Fascist Grand Council, and Vittorio Emmanuelle III, the King of Italy, reduced to a figure head by Mussolini, appointed Field Marshal Pietro Badoglio to be the new Prime Minister of Italy. Mussolini was arrested but later rescued by German paratroopers in a mountain top resort where he was imprisoned. After his rescue, he set up the Italian Socialist Republic in German-held northern Italy, with himself as its leader.
